Thermodynamic Analysis of Metal Segregation in Two Metal Boride-Carbide Ceramics Containing V with Cr, Hf, Ti, or Zr

Dual-phase carbide-boride ceramics in different vanadium-Me (Me = Cr, Hf, Ti, and Zr) binary systems were synthesized by boro/carbothermal reduction under stoichiometric and carbon-deficient conditions and densified by spark plasma sintering ...

Preliminary investigation of zirconium boride ceramals for gas-turbine blade applications

, 1953
Zirconium boride ZrB2 ceramals were investigated for possible gas-turbine-blade application. Included in the study were thermal shock evaluations of disks, preliminary turbine-blade operation, and observations of oxidation resistance. Thermal shock disks

Low-Temperature Deposition of Zirconium and Hafnium Boride Films by Thermal Decomposition of the Metal Borohydrides (M[BH4]4)

, 1988
Conductive (150 μω cm), adherent films of zirconium and hafnium borides have been deposited on various substrates by the low-temperature (100-270 °C) thermal decomposition of Zr[BH4]4 and Hf[BH4]4.

A study on radiation interaction parameters of boron carbide/zirconium boride composites

Applied Physics A
In this study, photon interaction parameters such as radiation protection efficiency (RPE), total mass attenuation coefficient (mu/rho), linear attenuation coefficients (mu), half value layers (HVL), tenth value layers (TVL), mean free paths (MFP), effective atomic numbers (Z(Eff)) and effective electron densities (N-Eff) were experimentally ...

Effect of carbon and titanium carbide on sintering behaviour of zirconium diboride

, 2008
Systematic sintering studies on the ZrB2 powder were carried out with the addition of carbon (C) in the range of 0 < x < 10 (x = wt.%) and (titanium carbide) TiC in the range of 0 < y < 30 (y = wt.%).
